所以讓我很認真的檢查設定檔
/etc/hosts.allow
/etc/hosts.deny
/etc/sshd/sshd_config
iptables -A INPUT -p tcp -dport 22 -J DROP
冒似沒啥問題

slackware與ubuntu網路設定不同處

Slackware其設定檔案的位置在於 /etc/rc.d/rc.inet1.conf 其中設定內容為

IPADD[0]="192.168.0.1" NETMASK[0]="255.255.255.0" GATEWAY="192.168.0.1"

至於在DNS設定方面則在 /etc/resolv.conf

nameserver 168.95.192.1 nameserver 168.95.1.1

然而在ubuntu14.0的部分在於其設定檔位在 /etc/network/interfaces 其中設定內容為

auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.1 netmask 255.255.255.0 gateway 192.168.0.1 dns-nameservers 168.95.192.1 168.95.1.1

因為ubuntu把設定都整合在一個設定檔中，如此可以一次將所需要的部分設定完整
